我国小型轧机有700多套,占全国轧机总数的三分之一以上,年产能力约2500万吨。 目前我国小型轧机中连续式和半连续式轧机(包括新建和经过技术改造的)仅有27套,只占小型轧机总数的4％,年产能力约为460万吨,明显不能适应我国发展轧钢要优化品种结构、优化装备结构、优化技术结构的需要,致使我国小型型钢生产产量低、成材率低、消耗高、质量难以提高和经济规模生产难以形成的状况,远不能适应我国钢材市场日益增长的需求。 为使我国小型轧机在90年代跟上国际技术发展大潮流,小型型钢轧机不能停留在横列式轧机的现状,而必须采用先进技术进行改造,走连续化或半
China has more than 700 sets of small mills, accounting for more than one-third of the total number of mills in the country, with an annual capacity of about 25 million tons. At present, only 27 sets of continuous and semi-continuous rolling mills (including newly-built and technically-modified ones) in our country’s small mills only make up 4% of the total number of small mills, with an annual capacity of about 4.6 million tons, which obviously can not meet the requirements of China’s development of rolling To optimize the variety structure, optimize the equipment structure, optimize the technical structure, resulting in China’s small-scale steel production is low, low yield, high consumption, quality is difficult to improve and economies of scale difficult to form the situation far can not meet the growing steel market in our country The demand. In order to make China’s small mill keep up with the tide of international technology development in the 90’s, the small section mill can not stay in the current state of the row mill, but must use the advanced technology to transform, take the continuous or half
